TUBE AND HEAD THEREFOR Filed Sept. 12, 1941 FIG- 2 INVENTOR CHARLES A. TOME Patented Oct. 19, 1943 t UNITED STATES eATENr OFFICE" 2,332,414 TUBE AND HEAD THEREFOR Charles A. Tome, Wilmington, Del. Application September 12, 1941, Serial No. 410,505

2 Claims.

This invention is an improvement over the invention described in my application Serial No.

some flexible, and preferably transparent, organic material such as cellulose acetate, the end of which is held in a head of plastic material by a flexible washer of reversible curvature.

It is an object of my invention to improve the head described in the said application. Another object of the invention is to support the washers which are used in assembling the elements of the tube. Other objects of the invention will be in part apparent and in part described hereinafter.

In.the drawing Figure 1 is a perspective view of my improved head. Figure 2 is a view of my improved head taken from below. Figure 3 is a section on line 111-111 of Figure 2 with the tube and washer added.

In the drawing like numerals refer to like parts. it is the head; H is a screw-threaded nozzle on the head; [2 is a skirt forming a part of the head, which is undercut as shown in Fi ure 3. I have discovered that for many uses the undercutting need not be in the form of a groove, as shown in my said application, but may be a conical undercutting beginning at the edge of the skirt. I3 is a flexible tube; M in a washer to hold the tube in place. Both the tube and washer are of the kind described in my said application. I5 is a conical boss forming an inward extension of the nozzle; l6 ar web-like supports integral with the head which both support the boss and may serve as stops and supports for the washer.

In assembling the device the conical boss receives the opening in the washer and serves to guide the washer to a properly alined position. Furthermore, when forces tend to collapse the 5 washer, the boss serves to support it and to pre vent its collapse. The webs 16 ar so constructed that they prevent the assembly machine from sliding the washer too far up the conical boss and splitting it at its opening,and they oppose any tendency of the washer to collapse by flexing.

As many apparently widely different embodiments of this invention may be made without departing from the spirit and scopethereof, it is to b understood that I do not limit myself to fined in the appended claims.

I claim:

'1. A tube having a flexible body, a comparaand having an annular skirt, a iiexible tube hav-Y ing a portion within said skirt, a, flexible washer acting to press the tube into sealed relation with the inside of the skirt and having a hole, and

means on th head extending through the said hole and acting to brace the washer, said means being perforated to permit ejection of the contents of the tube through the orifice.
